The forum aimed to enhance listed companies’ understanding of implementing SPK in line with global International Financial Reporting Standards (IFRS) S1 and S2 to boost information credibility and the capital market’s competitiveness.

Stakeholders stressed the importance of board leadership in integrating sustainability into business strategy and risk management. To support this, BEI continues to develop reporting infrastructure via the SPE-IDXnet system and IDX Sustainability website to provide transparent, high-quality ESG data for investors.

The IHSG continues to trend downward. Year-to-date in 2026, it has plummeted nearly 30% from its year-start level of 8,748.
